Firstly, you put the beef with the bones into a big pot and fill it with water. Then add the cut soup vegetables and parsley, so the carrots, celeriac and leek. Put some salt into the water and 4-5 peppercorns. Now let the soup boil for about 2 hours.
Then you can take out the meat, take it off the bones, cut it into pieces and put it back into the soup. Now you have the base for your soup. You can add all vegetables you like. I always have kohlrabi, brussel sprouts and peas in it. Then I also add some soup noodles and form little meatballs out of minced pork and add them to the soup. Now you let the soup cook for about 10-15 minutes and you can eat!
